Silverback Gorilla

A Silverback Gorilla is a mature male Mountain Gorilla weighing between 300 and 400 pounds. He is incredibly strong and lean and has massive canines (teeth). Females gorillas are 150 to 250 pounds. The gorilla diet consists of eating 40 plus pounds of vegetation and fruit daily. Gorillas are Herbivores and sometimes snack on termites, ants, and termite larvae but gorillas DO NOT eat meat or the flesh of other animals.

Chances are that you are reading this article because you are considering a vegetarian or vegan diet. Gorillas have a similar digestive system as a human. There are, however some major differences in what humans should consume versus a gorilla.

First, it should be noted that gorillas derive much of their Vitamin B12 from eating plants that are not washed in chlorinated water! Vitamin B12 is found in bacteria in soil. In addition, they eat termites and ants that are covered in nutrient rich soil. Humans wash much of their produce and the produce you buy is washed with chlorinated or purified water thus losing much of the nutrients that you might have otherwise derived from ingesting soil. It is also important to note that much of the agricultural products produced for humans are produced in soil that is mostly depleted of nutrients. It is paramount that humans have adequate amounts of Vitamin B12 and is highly recommended for vegans to take a Vitamin B12 supplement.

Humans have a smaller colon and a larger small intestine than gorillas and other primates. As a result, we require softer, less fibrous, and more nutrient and energy dense foods. It would be difficult for a human to digest much of the stems, leaves and seeds that are part of the diet of other primates. Thus the reason we crush, chop, and cook much of our produce and fibrous foods. It is believed that this is a result of the human agriculture revolution and human adaptation despite the ‘paleo diet’ myths out there.

In fact, the human oldest fossils now found dating 180,000 to 360,000 show that humans have been largely plant eaters by the fibers, grains, and seeds found in their teeth.

Since gorillas have larger colons, they ferment much of their plant fibers in their gut. The gorilla has six times the absorption available from the colon than a human does, which means they have many times the amount of bacteria available for digestion of plant cellulose. Humans pass most of the plant cellulose and are unable to digest it, and human capacity to convert plant fiber to fatty acid is quite limited. Fatty acids (especially Omega 3) are essential to human health.

Another big difference between humans and other primates and most other animals is the amount of amylase (a digestive enzyme) that we produce. This enzyme helps in the digestion and break down of starches like rice, wheat, maize (corn), and potatoes. It is likely that this is a direct result of adaptation as some studies show that cultures with a higher intake of starch (Japan) produce more amylase. In other words, humans are able to easily consume and process starchy foods and thrive on those starches. Some believe that humans are essentially ‘Starchivores’.

It is most likely that early humans lived in warm climates and ate the fruits of the what nature produced naturally. Namely fruits and nuts. As our population has grown, we rely on agriculture and foods that humans plant and produce. What we consume today may not be what early humans ate, but it does show that humans are highly adaptive.

Could we eat like a gorilla? A gorilla diet would allow for our survival but I don’t believe it is the most beneficial diet for a human. At the same time, the diet that most cultures eat today is dangerous to our health and the health of our planet. Obesity rates and chronic diseases have run rampant. Our planet is dying and if we don’t change what we are doing, we are destined for extinction.

If you are considering a vegetarian or vegan diet, I would highly recommend it for the benefit of your health and the benefit of this planet we share. All you have to do is look around you to know that our current course is not healthy. I can tell you from my personal experience that it changed my life! I would encourage you to do the research to ensure that you are getting the nutrients that you need in your diet and to not just ‘go vegan’ uninformed. I have many resources available on my blog. I would also encourage you to visit and download the smart phone app ‘Daily Dozen’.

A well balanced diet is important for your health and longevity so please know what you should and should not put in your body! I am very careful about my diet as there is a lot of longevity in my family, but there is also a lot of chronic disease like diabetes and heart disease. I will likely live into my 90’s and I plan to grow old gracefully!

P.S. Plants Have Protein!
